The Chinese have been planting Australian tree species for more than 100 years. Little is known, however, of the exact geographic origins of these trees. Collaborative tree species selection research was undertaken in southern China beginning in the early 1980's supported by the Australian Centre for International Agricultural Research (ACIAR), the Chinese Academy of Forestry (CAF) and the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO).
